WINDOW-SCREEN.

Specification of Letters Patent.

Patented Feb. 4, 1913.

Application filed July 18, 1911. Serial No. 639,077.

I the casing may be permanently secured to the window frame and the tension of the spring roller, mounted therein, may be regulated without removing the roller from. the casing.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawings, which form apart of this application,- and in which I Figure 1 is afront elevation showing the device applied. Fig. 2 is a side elevation thereof. Fig. 3 is a detail top plan view with a portion of the strip broken away to show the channel. -Fig. 4 is an inside elevation of the casing with the roller removed therefrom. Fig. 5 is a detail perspective view of the cap. s

Referring more particularly to the drawings, 1 represents a substantially semi-cy-' lindrical casing having a laterally extending flange 2 at its upper edge to receive fastening devices 3. 7 One end of the casing is closed by a cap 4 which is provided with a lateral flange 5 also provided with apertures to receive the fastening devices 6. Thiscap has projecting inwardly therefrom'a stud 7 upon which one end of the spring roller 8 is journaled. At the opposite end of the casing a strip 9 is secured therearound which forms a channel 10 for the reception of the semi-circular flange 11 which is secured to the end cap 12. This end cap is also provided with a lateral flange13 having apertures to receive the fastening devices 14 and is provided with a socket member 15 which extends inwardly therefrom, so as to engage the projecting end of the spring shaft 16.

Wound around the roller 8 is a quantity of screen fabric 17 upon the lower; end of which is secured a metallic'strip 18' having apertures therein to receive suitable attaching screws 19 preferably provided with hinged heads, so as to permit of convenient insertion within the sillor other portion of the window frame. The lower edge of the casing is preferably rolled, as shown at 20, so as to provide a smooth surface over which the fabric is adapted to travel and, in prac- .tice, the edges of the fabric are preferably confined in the guideways, not shown, so as to prevent any space between the fabric in therframe' where insects might gain access to theroom.

When it is desired to change the tension of the spring roller or decrease. said tension, the end cap 12 is removed and turned in the proper direction. This cap being provided with the boss 15 having the oval aperture therein which engages the oval extension of the shaft 16 will rotate the shaft and tighten the spring within the roller. The. cap may be then replaced with. the flange 11 lying in the channel '10, the stud 7 being suiliciently long to perinit the withdrawal of the roller sufficiently to withdraw the flange from the channel and easing.

Having thus described the invention, what I claim as new is 1. In a device of the class described, the combination with a casing, of a spring roller having a projecting spring shaft, means for journaling one end of the roller in the casing, and" a removable cap carried by the casing and having a socketed boss for holding the spring shaft of the roller. 3

2. In a device of the class described, the combination with a casing, of a spring roller mounted in the casing and having a pro jecting spring shaft, a stud carried by the casing for journaling one end of the roller within the casing, aremovable cap carried by the casing, a socketed boss upon the cap for receiving the spring shaftand supporting the opposite end of "the roller, and means for attaching the cap to'a support independent of the casing.
